Bella is Katniss' biggest fan. WhenJennifer Lawrencewon the Best Actress Oscar (for Silver Linings Playbook) on Sunday, Feb. 24, an eyewitness inside L.A.'s Dolby Theatre tells Us Weekly that no one was more excited for her than Kristen Stewart.

"When they announced Jen's name, Kristen was so happy and cheering for her!" an audience member tells Us. "She was going crazy in her seat."

In addition to being stars of big movie franchises, the two share another thing in common: they're both accident prone. Earlier in the evening, Lawrence saw Stewart using crutches and was photographed helping her on the red carpet. Later that night, the Oscar winner suffered her own mishap when she took a tumble -- as a billion TV watchers looked on! -- while ascending the stage to accept her award.

"She's so cool," Stewart told MTV News of Lawrence. "I was a lot younger than her when I first sort of entered this world of franchise land, and I don't know, I guess we sort of both went, 'Wow, this is so weird.' We were actually sat in a corner with Emma Watson as well, the three of us. We were like, 'Wow, this is strange. This is really cool.'"

"I think people assume that actresses don't want to [be friends]," she added. "It was kind of a great feeling, to be honest. I was like, 'This is kind of just awesome.'"
